Doug I mean no ill will at all, but I want to ask what your experience with NM is?
I believe you are in an area that pretty much denies the existence of the product.
I have grown up with NM and our buildings are not predominantly rats nests. NM just like pipe can be installed, modified, maintained in a neat and workmanlike way or it can be all hacked up. IMO it is the tradesman not the product that has the biggest influence on the job.
